[PATCH] bug in Util/helpfile

[Martin Vaeth <martin@xxxxxxxx>]

Hello,

in one of the last changes to Util/helpfiles a typo happened:
It was forgotten to pass the option "-" to colcrt which was always used,
previously; without this option inappropriate output is produced
(e.g. for underscores in variable names).
